HEATINQ AND COOLING DEVICE FOR INCLOSED SPACES Filed da 14, 1928 2 Sheets-Sheet 2 Patented Oct. 6, 1931 PATENT OFFICE LES'IEB A. JAMES, OF OKLAHOMA CITY, .OKLAHOIA HEATING AND COOLING DEVICE FOR INOIDSED SPACES 4 Application filed May 14, 1928. Serial No'. 277,552.

My invention relates to devices for controlling the temperature of inclosed cars and for coo ing and supplying drinking water therein. I ll The objects of the invention are to provide a device which will exhaust the air in the car b fan suction, force the air through a coo ing device where its temperature is lowered and then return it to the car; to provide a device which will also operate to heat the air by exhausting it from the car, forcing it through a'heater and back into the car; also to rovide a device for applying heat to the windshield so as to prevent the formation of frost thereon; also in connection with the cooling device to provide a supply of cold drinking water and having same easily 'accessible, as on the instrument board; to rovide such units for cooling .and heating w ich 90 are new, simple, light, strong, durable, in-

expensive, reliable and of evident utility; which cannot easily get out of order when once installed and which are eflicient for the purposes for which they are intended. With'these and other objects in view, my invention consists of the construction, novel features and combination of parts hereinafter more fully described, illustrated in the accompanying two sheets of drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, shape, weight and details of construction, within the scope of my invention may be resorted to without departing from the spirit or'principle of the invention or sacrificing any 0 the advantages thereof.

spective sectional view showing openings in parts adjoining the windshield; and Fig. 9 is a .fragmentary perspective view showing a I part of the cooling device and drinking water spigot. 5p.- ike numbers of reference will be used for the same parts throughout all the views.

Traveling salesmen, as well as others. whose business requires them to drive in all kinds of weather, suffer great discomfort from the co extremes in temperature. In cold weather it is difficult to keepthe hands and feet warm and there is danger in driving when frost and ice collects on and obstructs the view through the windshield. In warm weather 05 when windshield and windows must be left open for ventilation there is the annoyance of dust and insects, and the lack of a cold drinking water sup ly. 'My invention seeks to eliminate all of t ese annoyances and disadvantages. 7

In Figure 1, the numeral 1 represents the car body, 2 is the air suction pipe, 3 is a fan or blower operated by the fan motor 4, connected with the battery by line 5; the hose 6 73 connects the fan with thecooling device consisting of an outer casing 7 for insulating and inclosing the other parts of the cooler. At 8 is a bottom hollow ring member or mamfold into which the air is forced by the fan so through the hose 6. Here the air is split u into small currents and forced upwar through the air tubes 9, said tubes being surrounded by cold water; the cooled air currents in the said tubes 9 are collected in a top a; hollow ring member or manifold 10 ready to be forced through connection 21 as will be explained presently. Within the casing 7 of the cooler is the cold water cylinder through which the said tubes 9 ass. 'This consists of an outer shell 11 an an inner shell 12. At 13 is a water filling compartment provided with a filling tube and cap, 14. Within the said inner shell 12, but separated therefrom by an air space, is the ice and ice water tank 15, provided with a filling tube and cap 16,'the said cap having an air valve 17 by means of which air pressure may be supplied to the ice and ice water tank 15. As can best be seen in'Figs. 3 and 4 the outer casing 'Z of the cooler completely insulates. the water compartments so that onlya small amount of ice in the tank will be necessary to the 'efiicient operation of the cooler. Leading out from the bottom of the tank 15 is the drinking'water supply pipe 18 terminating in, a

'conyeniently placed spigot 19, provided with heat the car, the air circulates through. the

cooleras just described but without the use of ice, the damper in the bottom of vent 22 is opened by means ofhandle 26, the air is forced through connection 27 to the air heater 28, into distributing chamber 29 where it is broken up and passes through the hot air tubes 30 and into the collecting chamber 3.1, the said hot airtubes 30 and chambers 29 and 31 are mounted upon the exhaust manifold 32. After being heated the air is forced Y through passage 33 and hot airventilator 34 and into the car at the drivers feet, the said ventilator34 being provided with a damper 35'. Taking off from passage 33 is hot air pipe 36, with a conveniently placed valve 37, flexible connection 38 and hot air supply conduit 39 attached to the upper edge or any suitable place on the windshield .40 by suitable holding means 40a. By this means the glass is kept warm, thus preventin the forthrough the same at all times. In Fig. 5 is mation of frost and ice on both 'si es of the said windshield and assuring clear vision shown an alternate form of cooling vice consisting of an outer insulating shell 41, an

- ice and ice ,water tank 42 connected with a series of felt encased tubes 43 kept moist by the ice water, the air entering at 44, passing around and through the said tubes 43 and out at 45, thence to cool-air-vent 22.. Air pressure can be applied to tank 42, forcing the ice water out t rough pipe 46 andto" spigot 19. From the foregoing description it can be seen that'I provide means forkeeping the interior temperature of the car fairly con- 4 clear windshield during cold, sleety weather.
